Sulphur + sulphuric acid → sulphur dioxide + water

When the given equation is written in molecular form and balanced completely, the coefficient of sulphur dioxide is

The balanced and molecular form of the given equation is written as

  S (s)   +   2H₂SO₄ (aq)  →   3SO₂ (g)   +   2H₂O (l)

Sulphur   Sulphuric acid     Sulphur dioxide     Water
On balancing the given word equation, the coefficient of sulphur dioxide comes out to be 3.
